Use the variable “weight” as the dependent variable and “height” as the independent variable.
(a) Use Excel (or other statistical software) to finish the
Then compare your outputs from t-test and ANOVA table, and comment on
what you find.
(b) Construct a 99% confidence interval for the estimate of slope.
(c) Suppose we want to predict the height of student of heights 60, 65, and 70 inches. Give your prediction values and their prediction intervals.
